Ingredients

1 bag (30 oz / 850 g) frozen shredded hash browns, thawed
1 can (10.5 oz / 300 g) cream of chicken soup
1 cup (240 ml) sour cream
2 cups (200 g) shredded cheddar cheese, divided
½ cup (115 g) melted butter
½ cup (80 g) finely chopped onion
½ teaspoon garlic powder
½ teaspoon salt
¼ teaspoon black pepper
1½ cups (75 g) crushed cornflakes or buttery crackers
3 tablespoons melted butter for topping

Step-by-Step Instructions

Preparing the Ingredients

Start by preheating the oven to 350°F and lightly greasing a 9×13-inch baking dish, then thaw the hash browns completely and drain off any excess moisture so the casserole bakes evenly instead of turning watery.

Cooking Instructions

In a large bowl, stir together the cream of chicken soup, sour cream, melted butter, 1½ cups of cheddar cheese, onion, garlic powder, salt, and pepper until smooth, fold in the hash browns, spread the mixture into the dish, top with remaining cheese, finish with buttered cornflakes, and bake uncovered for 45 to 50 minutes until bubbly and golden.

Tips for Perfect Results

Common Mistakes to Avoid

One of the most common issues with a shredded hash brown recipe like this comes from skipping the thawing step, since frozen potatoes release liquid as they cook and can keep the casserole from setting properly.

Pro Tips for Better Flavor

For deeper flavor, sauté the chopped onion in a little butter before mixing it in, and consider using sharp cheddar so the cheese stands up to the rich base without tasting flat.

Serving and Storage

How to Serve

This cheesy potato casserole works beautifully alongside baked ham, roasted chicken, or breakfast eggs, and it can easily anchor a holiday spread or a relaxed weekend brunch.

How to Store Leftovers

Let leftovers cool fully, cover tightly, and refrigerate for up to four days, then reheat in the oven so the topping stays crisp instead of soft.
